Malaria management programmes—levels of prevention Urban malaria epidemiology
It is not well known if all of the standard
malaria prevention, management and control strategies can be effectively transferred to urban settings. While there is some evidence that anopheline species are adapting to urban aquatic habitats (e.g. water-filled domestic containers, back yard gardens), there is concern that misdiagnosis and subsequent inappropriate treatment of malaria is occurring.
All fevers cannot be presumptively assumed to be malaria in an urban setting. The typical clinical protocols that are employed in the countryside may not be valid in the city.

Research has shown that 50–70 per cent of the fevers in an urban setting are not laboratory proven malaria despite an initial clinical (non- laboratory) diagnosis to the contrary.Within an urban context, the cost-effectiveness of standard vector control strategies is also unknown.

Vector control in malaria
1. Reduction of human-vector contact by:
‘stopping Anopheles—a moving target' the use of bednets; improvements in housing (screening windows, eaves and doors); • identification repellants for skin and/or clothing; • resistance to insecticide dispensers (mosquito coils, plug-ins); and room preparation (spraying curtains, under bed, etc.).

Chemoprophylaxis involves taking a specific medication in order to prevent development of malaria. Each medication has its own spectrum of side-effects, dosage schedule of adminis- tration and indications and contra-indications.
Drug branding, marketing and advisory guide- lines are typically produced on a target country basis, since resistance profiles are constantly changing for the medications.The most current guidelines for the target country should always be consulted. In addition, appropriate local medical experts can also be consulted.
Regardless of the medication, the key concept PhotoLink/Getty Images Secondary and tertiary prevention of transmissible vector-borne diseases noted above, in some cases this is due to a small percentage of non-compliant individuals who do not take, or do not consistently take, the Compliance drug testing regimes, using urine testing for medication metabolites, have been implemented by some companies in the oil and gas industry as part of an overall Malaria Management Programme.

Therefore, individuals transferring between different malarious areas may need additional medical consideration. Chemoprophylaxis alone does not provide absolute protection; therefore, providing the full range of secondary prevention strategies is an important consideration.
Finally, with regard to compliance, it is important to note that the provision of antimalarials to employees in the field does not obviate the risk of contracting malaria. While in some cases this is due to poor absorption and/or variable therapeutic plasma levels, as Secondary and tertiary prevention of transmissible vector-borne diseases do not indicate malaria, travellers are encouraged to take Coartem® as a precaution.
Coartem® is now included in the World Health Organization (WHO) Model List of Essential Medicines, and is being distributed through the WHO as part of the worldwide Roll Back Malaria initiative.

illness has life threatening malaria. This recommendation will obviously produce ‘false-positives' and subsequent over-diagnosis of malaria; however, the medical rationale is that ‘false-negatives' are potentially at substantial risk for a fatal outcome due to missed diagnosis. This overriding concern related to delay in diagnosis has led to the rapid diagnostic tests (RDTs); and stand-by emergency treatment (SBT) kits.
When the test kit is well maintained, some RDT products can achieve a sensitivity (the ability to detect a ‘positive') for P. falciparum similar to that obtained by microscopy. RDTs can be damaged by exposure to high temper- ature extremes (heat or cold). If transport and storage within conditions specified by the manufacturer are not met, the sensitivity of the RDTs may be impaired and shelf life reduced.

time management
After the general scope has been determined, the planning process can begin. It is critical to identify at the outset the types of resources that may be required. Resourcing issues require careful consideration since multi-level, integrated MMPs draw expertise across many disciplines. While many oil and gas companies have large and sophisticated medical, environ- mental and safety departments, it is quite likely ofsky/Getty Images that some level of outside specialty expertise will still need to be considered, particularly related to the implementation of primary vector control strategies. For large projects, even secondary prevention strategies require cally identified and defined since it is quite significant levels of active on-site clinical likely that there will be multiple levels of medical support for accurate diagnosis and groups and organizations that will be both treatment.

Malaria is still be advisable to identify appropriate local a disease that has attracted worldwide attention resources, including medical practitioners and in virtually all areas where transmission is hospitals with appropriate malaria expertise and found. Therefore, it is highly likely that any proposed project in a known malarious area Implementing an MMP is potentially an will already be subject to some level of NGO, expensive undertaking and may require a national or international intervention control significant level of staffing.

Given this reality, the opportunity for is a function of the goals that the programme miscommunication and duplication of effort is wishes to achieve and the underlying level of significant.

This effort should be carefully contracting malaria to the lowest practicable planned and coordinated in a fashion that is level. Potentially, these goals can be achieved consistent with and responsive to overall but an intense, integrated and sustained effort using a variety of primary, secondary and tertiary strategies is likely to be needed.
Risk assessment is the process that investigates, appraises and qualitatively or quantitatively Stakeholder communication and consultation ranks the impacts, positive or negative, that is a process of mutual dialogue and information could be produced by a given activity. Many oil exchange between the project and the key and gas companies have internal risk assessment stakeholders. Stakeholders should be systemati- procedures and protocols covering health, Putting it all together: the MMP process is indicated. As previously discussed, the profile of malaria in urban and peri-urban settings is quite different than the intensity usually seen in a rural environment. If new data is deemed necessary, then a series of carefully defined study questions should be developed. These study questions are likely to cover vector species, habitat, and density in addition to objective burden of disease.
The ranking of potential impacts can be considered from an individual environmental, medical and sociological perspective or as an integrated exercise. Since malaria is a disease that operates at many levels, it may be more environmental, social and safety aspects of a efficient and meaningful to develop an proposed new business project.These processes integrated impacts ranking that considers not can be applied to MMP efforts.

The risk consider both the workforce and the assessment process can capture these differences and provide an appropriate way to rank impacts so that they can be address in a priority fashion.

All fevers are existing standard practices may be entirely actually not malaria even though in rural sufficient, e.g. a malaria visa programme. For malarious areas fever is ‘presumptively assumed' large, long-term projects, many companies have to be malaria and treated accordingly. Many established dedicated multi-disciplinary malaria studies have documented that malaria is management teams in order to simultaneously frequently misdiagnosed. If there is a concern manage both internal and external malaria that the project will impact the existing trans- issues. Senior management support, both at the mission pattern and burden of malaria, then project and corporate level, is essential since careful consideration should be given to sustainable MMP programmes are neither determine whether a new data collection effort simple nor inexpensive.

This sustainability required for an integrated plan specifies how high and how thick the ‘wall approach to malaria are neither simple nor of prevention' is constructed. The MMP is not cheap.

A system for An example of an audit form is included in determining that implementation has been accomplished and is achieving the desired results should be considered. Within the implementation and monitoring plan a system of outcome indicators is typically specified.
Auditing against these indicators can be readily performed. Contractor performance should also be verified and assessed for effec- tiveness and compliance. If the MMP is actively cooperating with host country programmes, these efforts should also be independently assessed against previously established outcome indicators.
A variety of audit systems for health programmes have been developed. General audits often cover: medical records and reports; facility inspections for vector control knowledge, attitude and practices (KAP) training records—topics, attendances and health care programme reviews and audits; emergency drills; and A simple way to remember the key steps A mosquito bite that introduces malaria needed to protect people from malaria: parasites into the bitten host Awareness - Bite prevention - International Petroleum Industry Chemoprophylaxis - Diagnosis Environmental Conservation Association Category (i.e. genus) of mosquito—some Indoor Residual Spraying—treatment of female species of Anopheles are capable houses where people spend night-time of transmitting malaria to humans and hours, by spraying insecticides that have a residual efficacy, i.e. they continue to Size of a health problem in an area, affect mosquitoes for several months measured by cost, mortality, morbidity, orother indicators Insecticide Treated bed Nets A method of attempting to prevent A parasitic disease that kills two million malaria by taking various drugs prior to, people per year around the world during, and after exposure to malaria Brand name of atavaquine-proguanil, a A new, life-saving malaria treatment drug used to prevent and treat malaria A drug used to prevent malaria that goes An insecticide (N,N,-diethyl-3- under the brand name of Lariam methylbenzamide) for use on exposed Malaria Early Warning System—a system skin to repel mosquitoes for predicting malaria epidemics based on A physical or mental impairment that substantially limits one or more major life Malaria Management Programme Proportion of the population who have a Exploration and Production particular disease Describes a disease that is localized to a Proportion of a population who have particular geographical region died from a particular disease The probable presence of malaria An expert on insects, such as Anopheles Term describing Anopheles mosquitoes that are active at night A sudden increase in the frequency of A person with no immunity to malaria malaria that significantly exceeds the International Association of Oil and Gas seasonal variation normally observed in a A microorganism, such as Plasmodium, The study of the incidence, distribution, that lives, grows and feeds in a different and control of disease in a population organism while contributing nothing to The human or animal in which the the survival of its host malaria parasite lives outside of the Parasites (including those causing malaria), bacteria, viruses or fungi that Protection generated by the body's can cause disease immune system in response to previous The functional changes in humans malaria attacks resulting in ability to resulting from infection by malaria control or lessen a malaria attack Incubation period The interval of time between infection Situation whereby malaria is spread by a malaria parasite and the onset of the throughout the year first symptoms of the illness.
